inDoc(node, win) causes Uncaught SecurityError

Vue.js version

1.0.23

Steps to reproduce

I embed a youtube link via jwplayer. The jwplayer is instantiated via a

<div id="jwplayer></div>

When certain manipluations via vue.js happen I get the error

JS ERROR: Uncaught SecurityError: Blocked a frame with origin "https://...." from accessing a cross-origin frame. .... Error: Blocked a frame with origin "https://...." from accessing a cross-origin frame.

From there on vue.js does not function properly.

What is Expected?

vue.js should not interfere with the iframe that is embedded via jwplayer.

What is actually happening?

The exception seems to happen here:

` /* * Check if a node is in the document. * Note: document.documentElement.contains should work here * but always returns false for comment nodes in phantomjs, * making unit tests difficult. This is fixed by doing the * contains() check on the node's parentNode instead of * the node itself. * @param {Node} node * @return {Boolean} */

function inDoc(node, win) {
    win = win || window;
    var doc = win.document.documentElement;
    var parent = node && node.parentNode;
    var isInDoc = doc === node || doc === parent || !!(parent && parent.nodeType === 1 && doc.contains(parent));
    if (!isInDoc) {
        var frames = win.frames;
        if (frames) {
            for (var i = 0; i < frames.length; i++) {
                if (inDoc(node, frames[i])) {
                    return true;
                }
            }
        }
    }
    return isInDoc;
}`

In the line:

var doc = win.document.documentElement;
